WARREN L. BOYER, 0F KINGSTON, NEW YORK.

ELECTRIC-RAILWAY lTRUQK.

Torall 'whom it may concern.' A

Be i yknown that I, WARREN L. BOYER, af citizen of the United States, and a resident of ",Kingstomin the county of Ulster and State of New York, have made and invented certain 4nevsl and? useful Improvements in Electric-Railway Trucks, of which the fllowing is a specification. Y. l

My invention relates to trucks designed for use supon electric railways for the purpose of supporting a' car body or one end thereof, and more particularly to trucks for electric railways'in which two-parallel axles truck being located at .each end of the car.

Heretofore the usual practice in providing t-rucks for electric railway'cars has been to design and build atruck frame' of sufficient strength to support a' carbody or one end thereof,v which truck frame is-'so designedv and arranged asito support thev electric motor which drives thel car; the frame being" thus designed with reference yto supporting car is operated. y y

As distinguished from the4above, my invention contemplates, and the object thereof both the car bodyV and the motor whereby the`- is to hp'rovide a single vunitary structure" adapted to' provide the .necessary casing or frame for the electric motor-,which loperates the car, and to provide also vfor supporting the axle or axles which in turn support. vthe truck from the track. It therefore follows that in vmy. improved truck the elements which `perform the `functionv `of supporting -the car body do y,not have to be'de'signed and arranged with reference to supportin the motortfr'ame or casing, as the motor ame or casingv itself serves in part as av truck frame and imparts strength thereto, as distinguished from being supported from a truck frame designed with .reference Vto supporting both t-hecar `body and the motor casing or frame. combined motor casing and truckframe constructed in accordance with my invention is therefore much lighter vthan is t-he case where a truck frame is `first provided for supporting both the car bodyy and the motor frame creasing, and, in cases where the motor and truck `frames are formed for the most part as a single casting,

as in the preferred embodiment of my invention, the structure as a whole is much slmpler and 1s made up of fewer parts than 5 is theA case where a truck frame is first pro- Jvid'ed, and a motor casing subsequently se- Specification of Letters atent," .Pate'nted Nv, 25, 1913, V* Application led January 25, 1913. lSerial No. 744,132.

vention in view, my invention consists in the improved combined motor` casing' and truck fra1ne illustrated in the accompanyin drawings andhereinafter described and c aimed,

suppo-rted'from and in's'uch variations and modifications vthereof as will be obvious to those skilled in the art to which my .invention relates.

In the drawings, Figure l is a .view 'showing 'one form of'my improved combined motor casmg and truck frame v1n side elevation,

the same being' taken upon a plane indicated by the line 1--1, Figi 2; Fig. 2 is a View showing the same in plan; Fig. 3 is a'view showing a slightly modified form of my improved combined motor casing and truck frame; and, Fig. 4 1s a fragmentary view showing a further modification thereof.- In the drawings, and referring first to Figs. 1 and 2, these views show a combined motor casingandtruck frame formed as a single'integral,castingand having a' por# tion' 5 whiclrforms the frame or 'casing for the electric motor which drives the car, the l parallel axles are provided. A suitable bol" ster 13 is carried by lthe combined motor casing 'and truck frame and Awhich bolster 1n turn supports one end of a car body. The

same being provided with suitable poles as Y will be understood to thereby provide a eld for the motor.,A The armature of the motor bolster illustrated is of the type commonly referred to as a swinging bolster, vand the" same 1s shown assupported by twov separate' sprm'gs'tt located 'one at each. ofits ends,land which springsare in turn supported from the 'cmnbined casing and frame, as will be understood; the combined 'motor casing and truck frame considered as a whole being lso formed. that the springs inA 'question are located wholly or for the most 'part below the upper surface thereof in a supporting truck` frame is designed with' order that the bolster itself and the bolster plate 15 carried thereby, will extend a minimum distance above the vcasin and from which it follows that t e car body will be supported as close to the truck as practicable. It will beunderstood, however, that a bolster other than' of the swinging type may be employed so lon as the spring or springslwhich support t esame are in turn so supported from the combined casing and frame that the car body will be supported close to the up er side of the truck. It will thus be seen t at the ortion of my combined motor casing an truck frame' which provides the frame or casing 5 for the driving motor forms a massive strengthening element for'the. entire truck and from which the arms 10 extend; and from which also the portion of the combinedcasin and frame which supports the' bolster, an the arms 11 also project; the whole being designed and.- arranged with reference merely to supporting the weight of the car and not with reference to supporting the driving motor in addition to the weight of the car; as is the case where reference to supporting a motor which in itself contributes no strength tothe truck as a whole.

In the form of my invention shownin Fig. 1, the motor frame or casing is provided with a spider at each side thereof, one of which is shown at 16,the purpose of which construction is to permit the armature of the motor to be removed from the field by a transverse or sidewise movement` thereof. In the form of my device shown in Fig. 4, however a portion17 of that part of the combined motor andtruck frame which 'provides the field for the vmotor is made removable, so that upon loosening the bolts 18, theportion 17 ma be swung downward about a hinge-19 an the armature of the motor thus removed by a downward as distinguished from a transverse movement.

The form of my inventionshownin Fig..

copi-es o! this patentfmay be obtained for frame,

the truck an a su` port for t e free louter -eportion of the fiel magnets, thus providing a more rigid structure and strengthen? ing the combined motor casing andV truck frame as a whole. l

In the drawings, while I have illustrated a truck as motor, it wi l be understood that my invention contemplates and includes also a combined motor casing and trucliV frame in which provision is made for two driving motors, one to drive each axle of the truck. Having-thus described and explained my invention, I claim and desire to secure by Letters Patent:

1. In a motor truck for electric railways, a combined motor casing and truck frame formed as a single unitary structure and having bearings adapted to receive a suportiug axle, spring supported from and t ower ends of which lie below the upper surface of said combined casing and frame, and a bolster supported by said'sprin 2. In a motor truck for electric ra ways, a combined motor casing and Atruck frame formed'integral with one another and havin bearings adapted to receive a su porting ax e, springs 'supported from and t e lower ends of which lie below the upper surface of said combined casing and frame, .and a bolster supported by saidA s rings.

3. In a motor truck for electric railways, a motor frame or casing having arms so arranged as to suppgrt two` parallel axles of the truck, and lster supporting means located between said axles and below the A. D. 1913.- I
